Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
Cable is more reliable since it runs underground and goes by fibre optic. Any unreliability is purely down to your ISP either badly configuring or using cheapy hardware. ( ruling out a digger cutting through the line which often happens )
DSL runs across copper telephone wires, and is effected by the weather, and also is subject to the bandwidth being reduced when shared by several people in the same area.
T1 is a dedicated business line at 1.5mb, which is very reliable, but cable speeds have long since surpassed it.
T3 is 43mb/s but the cost is very high.
All of these you get in the UK. I have a 3mb home blueyonder connection, and at work theres a 100mb/s connection.
